心理何以会影响药效呢?这是因为心理作用可使机体的机能状态发生变化,进而影响机体对药物的反应。就拿“安慰剂”止痛来说,大脑含有一种细胞,它们只对特定的物质发生反应,具有止痛作用的阿片分子作为特种物质作用于这些细胞时,细胞便活动并发挥作用,阻止神经冲动的传递,因而使病人的痛苦得以减轻。研究发现,人类大脑能产生类似阿片样的物质——脑啡呔,病人感受心理暗示后,能刺激大脑产生并释放这种物质。心理因素又反过来影响到了生理因素,从生理上发挥了治疗作用。 How psychology will affect the efficacy? This is because the psychological effects can make the body’s functional status changes, thereby affecting the body’s response to drugs. In the case of “placebo” pain, the brain contains a type of cell that responds only to specific substances. When an opiate molecule with an analgesic effect acts on these cells as a specific substance, the cell becomes active and prevents it Nerve impulse transmission, thus relieving the patient’s pain. The study found that the human brain can produce opioid-like substance - brain brown sugar, the patient feel psychological implications, can stimulate the brain to produce and release of this material. Psychological factors in turn affect the physiological factors, from the physiological play a therapeutic role.
